QUICK on UNIX - Session Hang after Network Cutoff

[Adrian.Hudson at eu.averydennison.com]

Hi Ghani,

You could try trapping hang ups and terminates.

For interactive users executing Quick, add this to one of the early lines 
of their profiles (or the system profile)

trap  "exit 0"  HUP  TERM 

Regards,


Adrian

QUICK on UNIX - Session Hang after Network Cutoff






Dear all,
I have a customer who is having problem with QUICK via Reflection remote 
connection. While QUICK is in session, the connection is lost and quick 
processes appear to be continually trying to read() from a pty which has 
no underlying telnet connection active any longer.  The code path they 
enter when the pty is in this state causes all to be woken at once. 
The system has so many 'quick' processes (depending on the number of sites 
connecting and lost connection) in this state that they are all 
waking/sleeping together and causing lots of extra CPU time in the 
scheduling related kernel code paths.
Powerhouse Version:  8.43.D1
UNIX Version: HP-UX 11.2
Appreciate any input.
Thanks & regards,
Ghani.
